Pest Control FAQs, answered by experts

Contact pest control if you have a stink bug infestation that you need to eliminate quickly. It’s difficult to kill them without crushing them and releasing their signature odor, or without using a toxic insecticide. Some homeowners have had luck with peppermint oil sprays or soapy water traps. But a professional exterminator will have the best advice and course of action.

Boric acid is among the harsher chemicals you can use in your home, and it poses risks whether ingested, inhaled, or touched. Kids and pets alike tend to put their hands and mouths on anything within reach, so it’s always a good idea to store boric acid in a spot they can’t get to and use it only when they’re not around for an extended period. When you use it, ensure they’re out of the house and fully clean up any trace of boric acid when you’re done because even a small amount can cause problems. 

It takes a few weeks to get rid of roaches in the kitchen for a small infestation, as the cockroaches will need to take the bait back to their nest to infect the others. For larger infestation, you may need to schedule multiple professional treatments, which could take several weeks or up to 6 months to get rid of the roaches fully.

Exterminators can get rid of your current ant problem, but they won’t prevent ants from coming back. So it’s important to implement ant preventatives to avoid future infestations.

The primary reason ants enter your home is to find food. If they can’t find any, they won’t survive. So, the most effective way to prevent ant infestations is to clean, clean, and clean some more. 

Keep your kitchen sparkling and wash your dishes immediately (or at least give them a quick rinse and wash off leftover food). Take out your garbage and compost as often as possible and tightly seal all your kitchen containers, especially the mason jars you use to hold your sugar—sugar is gold to ants.

You can also hire a local handyperson to help you prevent future ant infestations. The handyman can seal cracks and fix leaks throughout your home, which will keep any ants from entering.

Although it's easy to eliminate one or two harmless spiders yourself, professional spider exterminators have the tools, licenses, and expertise to reduce or remove major infestations effectively. They can also safely get rid of venomous black widow or brown recluse spiders and offer advice about preventative treatments to help defend against more infestations.
